The default is that measure levels are point estimates.
Entering Measure Levels in LDW
You enter or revise measure levels in LDW's Matrix view.
When you add a new measure, LDW assigns a default level on
that measure to each alternative in your analysis. Similarly, when
you add a new alternative LDW assigns a default level on each
measure in your analysis for the alternative. The default level for
a measure is its least preferred level. LDW will not automatically
adjust default levels if you later change the measure's range.
There are no restrictions on the numbers you can enter as levels.
In particular, there is no requirement that the number be within
the range you define for a measure in its properties dialog box.
However, if you are using labels, you must select one of the labels
defined in the measure's properties dialog box.
By default, the levels you enter in the Matrix view are numerical
point estimates. To use labels, select the properties dialog box for
the measure and check the "Use Labels" box. Then click the
"Labels" tab to define the list of acceptable labels.
To enter a probabilistic level, double click the cell for the level or
select the Matrix::Define Probability option. You will then see the
probabilities dialog box, where you can define a probability
distribution for that level. You can define the level as any of a
variety of probability distributions. The choices include Normal,
Uniform, and Discrete distributions. If your measure uses labels,
you can define a discrete probability distribution over the possible
labels.
You can find out more about defining point estimate, label, and
probabilistic measure levels on page 6-21.
Defining Levels With Measure Categories
You can use measure categories to define the levels of a measure
as weighted sums or averages of several sub-measures. The
measure categories are simplified measures with two differences
from regular measures. First, measure categories have no defined
range. Second, LDW does not convert measure categories to
common units. LDW combines the values from all of a measure’s
categories using a weighted sum. LDW then converts he
